Abstract:We developed a miniaturized optical probe, based on a customized Fiber Bragg Grating, for mechanical characterization of biological tissues with sub-millimeter spatial resolution. The probe is integrated inside a metallic cannula (16 gauge) used for clinical applications, and it is driven by a robotic arm (KUKA LBR Med 7). The optical sensor has a resolution of less than 1 mN and measures the force on controlled tissue indentations. The functionality of the sensor was assessed by means of different tests carri… Show more
